If an old ACER Aspire 1 model ZG8 and had been installed Ubuntu on it for the last number of years. I want to revert to Windows 7 Starter, I have the Windows activation key but can't find an ISO file anywhere. I don't have a windows 7 disk available to do this. Microsoft tell me to check with the laptop manufacturer. Where can I get the ISO for this version of windows?
Many thanks in advance to anyone who can be of help.
